This topper is the best one I have ever had! I have an air bed which still did not quite work for me, but with this topper, and adjusting the bed, I am able to get a perfect sleep! I did not like the waterproof cover for this topper because I felt too hot with it. I took it off and replaced it with my original mattress cover that I had purchased with my air bed and that solved the problem. Also, the delivery was very quick, and contents were in good condition. When I laid it out on the bed, it just unfolded itself and never any foam smell. The price was more than I would normally pay, but in this case I will definitely get my money's worth!
